BUNG-IVIALLET.

SPECIFICATION forming part of Letters Patent No. 7 55,633, dated March 29, 1904. Application filed February 16, 1903. Serial No. 143,526. (No model.)

To all whom it may concern.-

Be it known that I, JOHN M. DIETERLE, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Bung-Mallets, of which the following is a specification.

This invention relates to a new form of mallet for driving bungs into beer and other barrels, and provides not Only a more efficient and convenient mallet for this purpose, but combines therewith for the greater convenience of the barkeeper a wrench for the adjustment of the nuts and couplings of the pipe connections.

In the drawings, Figure 1 is a front elevational view showing the two parts of my device assembled. Fig: 2 is a similar view with one of said parts removed. Fig. 3 is a bottom plan view with the parts in position as shown in Fig. 1. Fig. 4 is a top plan view of the parts in the position in Fig. 7. Fig. 5 is a rear elevation of the removable piece carrying the wrench and the lugs. Fig. 6 is a side elevational View of the same, and Fig. 7 is a front elevational view showing the as sembled parts in position on a beer-pipe entering a cask or barrel.

In order to enable bartenders to draw beer through a faucet located in the bar, it is necessary that the faucet should be connected with the barrel by means of a pipe. This pipe 1 is introduced into the barrel 2 through a metal plug or bung 3, which is pierced with an aperture through which the pipe 1 runs. As compressed air is also forced into the barrel for the purpose of ejecting the beer under pressure, it is necessarythat the bung should fit. very tightly into the bung-hole, and it has been customary in the trade to hammer same in with an ordinary wooden mallet. The result has been sometimes to break the bungs, frequently to drive them in unevenly, allowing more or less of a vent for the air, and gradually to enlarge the holes in the casks or barrels, besides the inconvenience of applying the blows first to one side of the bung and then to. the other in the endeavor to drive it in equally all around. To obviate these disadvantages, I have provided a mallet which will act in a straight line upon the top of the bung and upon all parts of it equally.

My device consists of a solid-metal or other 1 heavy hollow cylinder with a segment of the peripheral wall thereof removed. While I have described this mallet as being in the form of a hollow cylinder, it should be understood that that is merely a characterization of its essential nature, while it may be formed, as shown in the drawings, with an enlarged head or hammering portion 1 and a reduced handle portion 5, and the contour of both these parts may obviously be varied at pleasure. This hollow cylinder, with the segment of its peripheral wall removed, is placed in the position on the pipe 1 shown in Fig. 7, and the removable member 6 is fitted up to the pipe in the segmental opening 7, before referred to, as also seen in Fig. 7, and the handle portion 5 is firmly grasped by the hand, so that the hollow cylinder and the removable piece 6 both fit around the pipe 1 and tightly against each other. with the parts thus firmly grasped in the hand the person who is tapping the bar- I rel slides it up and down on the pipe 1, with the result that the heavy weight of the mallet and the force of the blows are directed directly upon the top of the bung 3, as is clearly evident from Fig. 7 and the bung driven tightly into its place. Moreover, adjacent to the top of the hollow cylinder the edges of its peripheral walls are rounded, as at 8, and receive the projections 9, which abut against the shoulders 10, and thus form an upper bearing-surface for the removable piece 6. At the bottom of this removable piece 6 are formed the pair of lugs 11, which abut against the shoulders 12 in the base portion 4 of the hollow cylinder, thus affording a lower bearingplace for said removable part 6. The lugs 11, however, have an additional function, as they also abut against the shoulders 13, which prevents the removable part 6 from rising while the mallet is in use. have the semicircular recess 14 between them and as they are arranged in the form of a wrench, the bartender has in convenient form, in combination with his beermallet,'a wrench with which he can adjust the usual nuts and pipe-couplings connected with pipe 1. (Not As the projections 9' shown in the drawings.) The lugs at the ends of the removable piece serve the double function of a wrench and means for securing the piece Within the cylinder, the upper lugs 9 forming the wrench and the bottom lugs the securing means.

It is obvious that many minor changes may be made in the form and arrangement of the several parts Without departing from the nature and spirit of my invention.

What I claim, and desire to secure by Letters Patent, is

A device of the character described comprising in combination With a hollow cylinder provided in its wall with a vertically-disposed segmental opening and shoulders arranged adjacent the ends of said opening, of a removable member arranged in said segmental opening, and lugs formed integral with the upper and lower ends of the said member on opposite sides thereof, the upper lugs forming a wrench member and the lower lugs securing the removable member in place, substantially as described.

In testimony whereof I have afiixed my signature, in presence of two witnesses, this l ith day of February, 1903.

JOHN M. DIETERLE.
